Across Eugene, Springfield, and Junction City, the dry air and clear skies will allow rapid cooling late tonight. Early commuters could feel a brisk chill, especially on exposed roads and rural routes. While no frost advisory is posted, colder pockets may form in low-lying areas. Keep a jacket ready and allow a few extra minutes for the morning start.
Tuesday brings a noticeable cooldown with highs near 65°F under partly sunny skies. By Wednesday, temperatures rebound slightly to near 67°F with mostly sunny conditions, offering a comfortable midweek stretch.
Clouds begin increasing Thursday, and a slight chance of showers develops after late morning. Roads could become slick during the first rainfall after several dry days. Light rain chances continue into Friday, with occasional breaks of sunshine.
Looking ahead, a more unsettled pattern may linger into the weekend with additional rain chances and cooler highs near 60°F.
